【Abstract】 A finite element method model of three dimension vibration analysis for a fin stabilited sabot discarded penetrator is established. Natural frequency and vibration model of some project fin stabilited sabot discarded penetrator during launching are calculated and analyzed. The vibration modes of the projectile are simulated under resonance. Influences of vibration characteristics of the projectile on gun projectile system are discussed. The research achievement provides an advanced engineering method for engineering design and accident analysis of fin stabilited sabot discarded penetrator.更多还原
